2013년 3월 팅 교수는 AMS가 400,000개 이상의 [[양전자]]를 관찰했으며 양전자 대 전자 비율이 10 GeV에서 250 GeV로 증가했다고 말하면서 초기 결과를 보고했다. (이후 결과에서는 약 275 GeV 이상의 에너지에서 양전자 분율이 감소하는 것으로 나타났다.) 시간에 따른 큰 변화나 선호하는 들어오는 방향은 없었다. 이러한 결과는 우주에서 암흑 물질 입자의 소멸에서 발생하는 양전자와 일치하지만 아직 다른 설명을 배제할 만큼 충분히 결정적이지는 않다. 결과는 [[피지컬 리뷰 레터]]에 게재되었다.<ref name="physrevltrs413">{{저널 인용| last1 = Aguilar | first1 = M. | last2 = Alberti | first2 = G. | last3 = Alpat | first3 = B. | last4 = Alvino | first4 = A. | last5 = Ambrosi | first5 = G. | last6 = Andeen | first6 = K. | last7 = Anderhub | first7 = H. | last8 = Arruda | first8 = L. | last9 = Azzarello | first9 = P. | last10 = Bachlechner | first10 = A. | last11 = Barao | first11 = F. | last12 = Baret | first12 = B. | last13 = Barrau | first13 = A. | last14 = Barrin | first14 = L. | last15 = Bartoloni | first15 = A. | last16 = Basara | first16 = L. | last17 = Basili | first17 = A. | last18 = Batalha | first18 = L. | last19 = Bates | first19 = J. | last20 = Battiston | first20 = R. | last21 = Bazo | first21 = J. | last22 = Becker | first22 = R. | last23 = Becker | first23 = U. | last24 = Behlmann | first24 = M. | last25 = Beischer | first25 = B. | last26 = Berdugo | first26 = J. | last27 = Berges | first27 = P. | last28 = Bertucci | first28 = B. | last29 = Bigongiari | first29 = G. | last30 = Biland | first30 = A. | title = First Result from the Alpha Magnetic Spectrometer on the International Space Station: Precision Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5–350 GeV | doi = 10.1103/PhysRevLett.110.141102 | journal = Physical Review Letters | volume = 110 | issue = 14 | pages = 141102 | date = 2013 |bibcode = 2013PhRvL.110n1102A | display-authors = 29 | pmid=25166975| url = https://boa.unimib.it/bitstream/10281/44680/1/2013_PhysRevLett.110.141102_positron_fraction.pdf | doi-access = free }}</ref> 추가 데이터는 계속 수집되고 있다.<ref name="physrevltrs413" /><ref name="AMS-20130403">{{웹 인용|author=Staff |title=First Result from the Alpha Magnetic Spectrometer Experiment |url=http://www.ams02.org/2013/04/first-results-from-the-alpha-magnetic-spectrometer-ams-experiment/ |date=April 3, 2013 |work=AMS Collaboration |access-date=April 3, 2013 |archive-url=https://web.archive.org/web/20130408185229/http://www.ams02.org/2013/04/first-results-from-the-alpha-magnetic-spectrometer-ams-experiment/ |archive-date=April 8, 2013 |url-status=dead }}</ref><ref name="AP-20130403">{{뉴스 인용|last1=Heilprin |first1=John |last2=Borenstein |first2=Seth |title=Scientists find hint of dark matter from cosmos |url=http://apnews.excite.com/article/20130403/DA5E6JAG3.html |date=April 3, 2013 |work=[[AP News]] |access-date=April 3, 2013 |archive-url=https://web.archive.org/web/20130510152050/http://apnews.excite.com/article/20130403/DA5E6JAG3.html |archive-date=May 10, 2013 |url-status=dead  }}</ref><ref name="BBC-20130403">{{뉴스 인용|last=Amos |first=Jonathan |title=Alpha Magnetic Spectrometer zeroes in on dark matter |url=https://www.bbc.co.uk/news/science-environment-22016504 |date=April 3, 2013 |work=[[BBC]] |access-date=April 3, 2013 }}</ref><ref name="NASA-20130403">{{웹 인용|last1=Perrotto |first1=Trent J. |last2=Byerly |first2=Josh |title=NASA TV Briefing Discusses Alpha Magnetic Spectrometer Results |url=http://www.nasa.gov/home/hqnews/2013/apr/HQ_M13-054_AMS_Findings_Briefing.html |date=April 2, 2013 |work=[[NASA]] |access-date=April 3, 2013 }}</ref><ref name="NYT-20130403">{{뉴스 인용|last=Overbye |first=Dennis |title=New Clues to the Mystery of Dark Matter |url=https://www.nytimes.com/2013/04/04/science/space/new-clues-to-the-mystery-of-dark-matter.html |date=April 3, 2013 |work=[[The New York Times]] |access-date=April 3, 2013 }}</ref><ref>{{웹 인용| url=http://home.web.cern.ch/about/updates/2013/04/ams-experiment-measures-antimatter-excess-space | title=AMS experiment measures antimatter excess in space}}</ref>
