The double-beta-decay experiment NEMO-3 has been taking data since February 2003. The aim of this experiment is to search for neutrinoless (0 {nu}{beta}{beta}) decay and investigate two neutrino doublebeta decay in seven different isotopically enriched samples ({sup 100}Mo, {sup 82}Se, {sup 48}Ca, {sup 96}Zr, {sup 116}Cd, {sup 130}Te, and {sup 150}Nd). After analysis of the data corresponding to 3.75 yr, no evidence for 0 {nu}{beta}{beta} decay in the 100Mo and 82Se samples was found. The half-life limits at the 90% C.L. are 1.1 Multiplication-Sign 10{sup 24} and 3.6 Multiplication-Sign 10{sup 23} yr, respectively. Additionally for 0 {nu}{beta}{beta} decay the following limits at the 90% C.L. were obtained, >1.3 Multiplication-Sign 10{sup 22} yr for {sup 48}Ca, >9.2 Multiplication-Sign 10{sup 21} yr for {sup 96}Zr, and >1.8 Multiplication-Sign 10{sup 22} yr for 150Nd. The 2 {nu}{beta}{beta} decay half-life values were precisely measured for all investigated isotopes.
