The intensity of the incoming 1485900100025 beam was monitored using a downstream ionization 1485900100026 chamber. 1485900100027 SAMPLE The 15C beam bombarded a target of deuterated 1485900100028 polyethylene (CD2)n of thickness 363(20) microg/cm2 1485900100029 or polyethylene (CH2)n of thickness 387(22) 1485900100030 microg/cm2, which corresponded to the measurement of 1485900100031 15C(p,d)14C and 15C(d,t)14C, respectively. 1485900100032 METHOD (EDE) The kinematic reconstruction was achieved 1485900100033 through high precision position-sensitive silicon 1485900100034 detector arrays, which provided both position and 1485900100035 energy information. This approach enabled the 1485900100036 extraction of differential cross sections for 1485900100037 transfer reactions populating the ground state (g.s.) 1485900100038 of 14C, covering a range of center-of-mass angles 1485900100039 (c.m.) from 15 to 35 degrees. 1485900100040 HISTORY (20251007C) BP 1485900100041 ENDBIB 39 0 1485900100042 NOCOMMON 0 0 1485900100043 ENDSUBENT 42 0 1485900199999 SUBENT 14859002 20251007 20260228 1485900200001 BIB 4 13 1485900200002 REACTION (6-C-14(N,G)6-C-15,,SIG,,,DERIV) 1485900200003 ANALYSIS The spectroscopic factors (SF) and asymptotic 1485900200004 normalization coefficient (ANC) of the 15Cg.s. were 1485900200005 determined from angular distributions using the 1485900200006 distorted-wave Born approximation (DWBA) theory.
