ENTRY 33021 20160929 31753302100000001 SUBENT 33021001 20160929 31753302100100001 BIB 14 53 3302100100002 TITLE Effect of shell closure proximity on fragment angular 3302100100003 momenta in 241-Pu(n,F) 3302100100004 AUTHOR (S.P.Dange,H.Naik,T.Datta,R.Guin,Satya Prakash, 3302100100005 M.V.Ramaniah) 3302100100006 INSTITUTE (3INDTRM) 3302100100007 REFERENCE (J,JRN/L,108,269,1987) 3302100100008 FACILITY (REAC,3INDTRM) Research Reactor APSARA in B.A.R.C, 3302100100009 Trombay, Mumbai 3302100100010 SAMPLE Electrodeposited target of 241-Pu (~50 micro gram) 3302100100011 covered with 0.00254 cm thick superpure aluminium 3302100100012 foil was irradiated in the Apsara reactor at a flux 3302100100013 of 2.0x10**12 n/cm2/sec. 3302100100014 METHOD (REC,CHSEP,GSPEC) Fission products were collected 3302100100015 using recoil catcher technique. Tellurium and iodine 3302100100016 were separated using standard radiochemical procedure 3302100100017 after dissolution of the catcher foil within 20-30 3302100100018 min from the end of the irradiations. After the 3302100100019 separation the samples were counted on a 45c.c. HPGe 3302100100020 detector in conjunction with a 4k analyzer in live 3302100100021 time mode. 3302100100022 DETECTOR (HPGE) The resolution of the detector system was 2.6 3302100100023 keV at 1332.0 keV. The dead time was maintained below 3302100100024 10%. 3302100100025 ANALYSIS (AREA) Linear Compton subtraction was done while 3302100100026 computing the peak areas under the photo peaks of 3302100100027 interest. The gamma-ray spectra of the separated 3302100100028 samples were checked for the absence of the precursor 3302100100029 activities. The observed activity profiles as a 3302100100030 function of time were analyzed using standard decay 3302100100031 growth equations to arrive at the separation time 3302100100032 activities of the meta-stable and ground states. 3302100100033 ERR-ANALYS (DATA-ERR) The quoted limits of errors on the 3302100100034 independent yield ratios were obtained taking into 3302100100035 account the observed precision with errors in 3302100100036 calculated peak area statistics, precursor yield 3302100100037 values and the least square fitting of the activity 3302100100038 profiles. The limits of the error on the RMS angular 3302100100039 momentum value arise from the errors on the 3302100100040 independent isomeric yield ratios. 3302100100041 DECAY-DATA The details of the isobaric decay chains involved in 3302100100042 the work, the yield of the fission product monitor 3302100100043 along with the relevant nuclear spectroscopic data 3302100100044 taken from: 3302100100045 B.F.Rider, Vallecitos Nuclear Centre, Report NEDO- 3302100100046 12151-1/1981/unpublished and 3302100100047 E.A.C.
