TAPE9 Contains the parameters needed to approximately reproduce the γ-energy dependence of theGe detector solid angle attenuation coefficients Q k ( see Section 4.3 ). TAPE9 is written when OP,GDETis executed and automatically read in when OP,YIEL is encountered, which implies that TAPE9 shouldbe attached to any job involving the calculation of γ yields.TAPE11 Contains the internal correction factors ( see Section 4.5 ) created and updated whenOP,MINI is executed. TAPE11 is required as an input file if the CONT switch CRF, was selected.CRF, causes GOSIA to read the internal correction factors from TAPE11 instead of calculating themwhen OP,MINI is encountered. Obviously, TAPE11 is to be saved after a previous run to use the timesavingCRF, switch when resuming the minimization. The internal correction factors are updated (and stored on TAPE11 ) every time the TEST criterion of the OP,MINI input ( 5.17 ) is fulfilled, thusthe internal correction coefficients stored on TAPE11 will correspond to the last set of matrix elementsfor which the update, defined by TEST, was done. In addition, the internal correction coefficients canbe calculated using the CONT switch CCF, for a given set of matrix elements. In this case TAPE11should be saved and defined as an input file for the subsequent run using the CONT CRF, switch.TAPE12 Contains the set of matrix elements resulting from the last minimization run. TAPE12 isoverwritten after completion of each OP,MINI command. The values of the matrix elements stored onTAPE12 can be used instead of those specified in the ME input using the OP,REST command beforethe selected executable option. An existing permanent file must be assigned to TAPE12 if OP,RESTis used.TAPE14 An output file for OP,SIXJ. Contains the table of Wigner’s 6 − j symbols to be used bySIGMA. TAPE14 also serves as an internal file when OP,INTG, OP,CORR, OP,TROU or OP,MINIwith the calculation of the sensitivity maps ( see Section 4.5 ) are executed.TAPE15 Contains the current set of errors of the matrix elements calculated by OP,ERRO. TAPE15 iswritten by OP,ERRO if IREP =0( see Section 5.6 ) and read, updated and overwritten if IREP =1.Internal for OP,INTG, OP,CORR and OP,TROU.TAPE17 An output file for OP,ERRO, containing the best (i.e. yielding the lowest value of x2) setof matrix elements found during the scan of the x2 hypersurface (see Section 4.6). Also serves as theoutput file to write the statistical tensors after Coulomb excitation using the CONT switch TEN, inconjunction with either OP,STAR or OP,POIN (see Section IV.3). The structure of this file, which maybe used by external programs to examine the g decay following the Coulomb excitation is as follows:Nρ 00ρ 20 ,ρ 21 ,ρ 22ρ 40 ,ρ 41 ,ρ 42 ,ρ 43 ,ρ 44ρ 60 ,ρ 61 ,ρ 62 ,ρ 63 ,ρ 64 ,ρ 65 ,ρ 66here N is the level index as defined by the sequence of the input to LEVE. The tensors for the groundstate N=1 are not stored, thus 2 < N < NMAX where NMAX is the number of levels included. Thissequence is repeated for each experiment according to the sequence of the input to EXPT. Note thatbecause of the symmetry rkm =(-1)mrk-m only the components with m > 0arestored.TAPE17isalso used as an internal file by OP,TROU and OP,INTG.129
