Chronological implications of changes in the accumulation rate of long marine cores from the continental shelf, southeastern Korea
Three long marine cores collected from the southwestern part of the Ulleung Basin in the East Sea were investigated in terms of chronology, from the middle Pleistocene to Holocene. We propose an age–depth mode...

Thickness analysis of LiF thin films by using 7Li(p,n) and 19F(p,αγ) nuclear reactions
A neutron time of flight (n-TOF) technique is applied for analyzing the thickness of a LiF thin film used as a neutron target. Measuring the flight time of the neutron generated from the neutron target gives i...
