MRC1

Nuclear reactions determine the life times

of stars and our sun – 6 billion years

Nuclear reactions drive

stellar explosions – 6 milliseconds

Nuclear processes are the

engine of the Universe !

The active (radioactive) Universe

14 n p 15 o and the limits of measurement
14N(p,)15O and the limits of measurement

MRC1

Top line is previous accepted value; bottom line is present measurement.

New experiments at

LUNA, LENA, TAMU

confirm lower S-factor

extrapolation !

  • reduction of total reaction rate
  • increases globular cluster age by ~1 billion years
slide8
MRC2

Each heavy atom in our body was built

and processed through ~40 supernova

explosions since the beginning of time!

We are made of star stuff

the pan program
The PAN program
  • Why?
  • To educate teachers and young students about nuclear astrophysics
  • To create awareness of the research being performed in this field
  • To interest young people in nuclear (astro) physics (career option?)
  • How?
  • Lectures to provide theoretical back ground
    • By NSCL Faculty on a wide variety of subjects
  • Hands-on! Built a cosmic ray detector, decay lab.
  • Stimulate informal discussion
  • Program aimed at providing material that can be used in the class room
  • Teach general data analysis skills
