자연계에 존재하는 레늄의 동위 원소는 185Re, 187Re이 있다. 185Re은 안정 동위 원소이며, 187Re은 방사성 동위 원소인데 187Re이 자연계에서 존재비가 62.6%로 방사성 동위 원소의 존재비가 많다. 187Re은 오스뮴-레늄 연대 측정에 쓰인다. == == 핵자수 Z(p) N(n) 동위 원소 질량 (u) 반감기 붕괴방식ε: 전자 포획IT: 이성질핵 전이 붕괴 생성동위 원소 핵스핀 자연계에 존재하는동위 원소범위(몰 분율) 자연계에 존재하는최대 범위(몰 분율) 들뜬 에너지 160Re 75 85 159.98212(43)# 860(120) µs0.82(+15-9) ms (91%) 159W (2-) (9%) 156Ta 161Re 75 86 160.97759(22) 0.37(4) ms 160W 1/2+ 161mRe 123.8(13) keV 15.6(9) ms 157Ta 11/2- 162Re 75 87 161.97600(22)# 107(13) ms (94%) 158Ta (2-) β+ (6%) 162W 162mRe 173(10) keV 77(9) ms (91%) 158Ta (9+) β+ (9%) 162W 163Re 75 88 162.972081(21) 390(70) ms β+ (68%) 163W (1/2+) (32%) 159Ta 163mRe 115(4) keV 214(5) ms (66%) 159Ta (11/2-) β+ (34%) 163W 164Re 75 89 163.97032(17)# 0.53(23) (58%) 160Ta high β+ (42%) 164W 164mRe 120(120)# keV 530(230) ms (2#)- 165Re 75 90 164.967089(30) 1# β+ 165W 1/2+# 161Ta 165mRe 47(26) keV 2.1(3) β+ (87%) 165W 11/2-# (13%) 161Ta 166Re 75 91 165.96581(9)# 2# β+ 166W 2-# 162Ta 167Re 75 92 166.96260(6)# 3.4(4) 163Ta 9/2-# β+ 167W 167mRe 130(40)# keV 5.9(3) β+ (99.3%) 167W 1/2+# (0.7%) 163Ta 168Re 75 93 167.96157(3) 4.4(1) β+ (99.99%) 168W (5+,6+,7+) (0.005%) 164Ta 168mRe non-exist 6.6(15) 169Re 75 94 168.95879(3) 8.1(5) β+ (99.99%) 169W 9/2-# (0.005%) 165Ta 169mRe 145(29) keV 15.1(15) β+ (99.8%) 169W 1/2+# (0.2%) 164Ta 170Re 75 95 169.958220(28) 9.2(2) β+ (99.99%) 170W (5+) (0.01%) 166Ta 171Re 75 96 170.95572(3) 15.2(4) β+ 171W (9/2-) 172Re 75 97 171.95542(6) 15(3) β+ 172W (5) 172mRe 0(100)# keV 55(5) β+ 172W (2) 173Re 75 98 172.95324(3) 1.98(26) min β+ 173W (5/2-) 174Re 75 99 173.95312(3) 2.40(4) min β+ 174W 175Re 75 100 174.95138(3) 5.89(5) min β+ 175W (5/2-) 176Re 75 101 175.95162(3) 5.3(3) min β+ 176W 3+ 177Re 75 102 176.95033(3) 14(1) min β+ 177W 5/2- 177mRe 84.71(10) keV 50(10) µs 5/2+ 178Re 75 103 177.95099(3) 13.2(2) min β+ 178W (3+) 179Re 75 104 178.949988(26) 19.5(1) min β+ 179W (5/2)+ 179m1Re 65.39(9) keV 95(25) µs (5/2-) 179m2Re 1684.59(14)+Y keV >0.4 µs (23/2+) 180Re 75 105 179.950789(23) 2.44(6) min β+ '''''180W''''' (1)- 181Re 75 106 180.950068(14) 19.9(7) β+ 181W 5/2+ 182Re 75 107 181.95121(11) 64.0(5) β+ '''182W''' 7+ 182m1Re 60(100) keV 12.7(2) β+ '''182W''' 2+ 182m2Re 235.736(10)+X keV 585(21) ns 2- 182m3Re 461.3(1)+X keV 0.78(9) µs (4-) 183Re 75 108 182.950820(9) 70.0(14) '''183W''' 5/2+ 183mRe 1907.6(3) keV 1.04(4) ms IT 183Re (25/2+) 184Re 75 109 183.952521(5) 38.0(5) β+ '''184W''' 3(-) 184mRe 188.01(4) keV 169(8) IT (75.4%) 184Re 8(+) β+ (24.6%) '''184W''' 185Re 75 110 184.9529550(13) '''안정''' 5/2+ 0.3740(2) 185mRe 2124(2) keV 123(23) ns (21/2) 186Re 75 111 185.9549861(13) 3.7186(5) β- (93.1%) '''''186Os''''' 1- (6.9%) '''186W''' 186mRe 149(7) keV 2.0(5)×105 IT (90%) 186Re (8+) β- (10%) '''''186Os''''' 187Re 75 112 186.9557531(15) '''41.2(2)×109 a''' β- (99.99%) '''187Os''' 5/2+ 0.6260(2) (10−4%) 183Ta 188Re 75 113 187.9581144(15) 17.0040(22) β- '''188Os''' 1- 188mRe 172.069(9) keV 18.59(4) min IT 188Re (6)- 189Re 75 114 188.959229(9) 24.3(4) β- '''189Os''' 5/2+ 190Re 75 115 189.96182(16) 3.1(3) min β- '''190Os''' (2)- 190mRe 210(50) keV 3.2(2) β- (54.4%) '''190Os''' (6-) IT (45.6%) 190Re 191Re 75 116 190.963125(11) 9.8(5) min β- 191Os (3/2+,1/2+) 192Re 75 117 191.96596(21)# 16(1) β- '''192Os''' 193Re 75 118 192.96747(21)# 30# >300 ns 5/2+# 194Re 75 119 193.97042(32)# 2# >300 ns == 각주 == 동위 원소 분류:원소별 동위 원소 목록
